// Open database
Alfred.open('path/to/db', function(err, db) {

  var User = db.define('User', {
    indexes: [{name: 'age',
              fn: function(user) { return user.age; }]
  });
  User.property('name', 'string', {
    maxLength: 100
  });
  User.property('active', 'boolean');

  // get user by id
  User.get(id, function(user) {
    console.log(user.inspect());
  };
